Application July 3, 1937, Serial No. 151,785 Y 7 Claims.v

particularly to an improved ink pad especially designed for use with ink cream.

An object of the invention is. to provide an improved pad the advantages of which are based upon a pumping action by which a pressure action upon the ink takes place, and whereby the feeding of the pad proper is eiiicviently accomplished. v

. Another object of the invention is to provide a simply constructed pad of the shape and height of the standard ink pads in consequence of which my improved pad does not require any special kind of outer container, but on the contrary my improvement may be applied to a standard type container.

An additional object of my invention is to provide a combination of parts in which ink paste or ink cream may be used, the advantage of such paste or cream being vthat it provides an efficient means by which ink is maintained for a long time before evaporation. Even after a protracted period of use of. the pad, the ink cream will still be available, since such pasteor cream will be absorbed in the pad proper after having been removed from the container. An added advantage of ink paste is that it aii'ords a uniform supply of ink and facilitates the fllling of the container.

For these purposes and advantages, my invention consists of an improved ink pad comprising an outer container having an open side, a closure of inherently resilient and yieldable material with a plurality of openings for closing said open side and spaced from the bottom of the container. A relatively rigid member provided with openings, is superimposed upon part of said yieldable member and a pad material placed over the rigid member envelops the resilient and rigid members, and is held between the resilient member and the inner walls of the outer container. Means for filling are provided as well as a cover for the pad material.

' Other features of. the invention will be more fully described hereinafter, and an embodiment of the invention will be shown in the drawing, and nally pointed out in the subjoined claims.

In the accompanying drawing:-

Figure 1 is a plan view showing parts broken away;

Figure 2 is a longitudinal vertical section taken on line 2-2 of Fig. 1; and l Figure 3 shows the various parts spaced from each other in elevated position from the front of the ink pad, the cover of the container not being shown.

Similar characters of reference indicate corresponding parts throughout the several views..

Referring-to the drawing, and more particularly to Fig. 3, the lowermost section illustrates A (ci. en -54.5) This invention relates toink pads, and more a portion ofa standard type outer container I0, which may be made 'of tin or the like. This outer container III carries a hinged cover II afscrewthreaded as shown by I 4, and closed by the screwthreaded member I5, the latter having a slot I6 to enable it to be rotated; and by such rotation it may be opened or closed.A Instead of slot I6, a handle may serve the same purpose. The felt-like member I3 is cut away, as at and may be raised or lowered, as shown by the position of the dotted lines at I8. The container may be supplied with either ink or paste by rst removing member I5, injecting the ink into the container, and then closing the member I5. The supply of ink reaches a. line preferably tothe level approximating the reference character I9,

in Fig. 2. The level indicated by I9 is arbitrarily chosen to generally show the extent of thefilling, or it may be higher and in actual contact with the under surface of the member immediately above, or, the supply of ink may reach below that shown. Above the selected height of the ink paste, as illustrated by I9, a horizontal member 20 is superimposed in which is contained a plurality of openings 22 throughout its length and breadth, and said member 20' may be made of rubber or other suitable material. The marginal portions of said member 20 are circumferentially curved, as seen at 2|, and these portions extend downwardly as at 23 and remain parallel with the lateral inner walls Illa of the container I0; and it will be noted that the curved marginal portions 2| extend above the edges of container I 0. superimposed upon said member 20 longitudinally thereof, is a rigid plate designated by 25 containing a plurality of openings throughout as 26 the diameter of which is smaller than that of openings 22; and said openings 22 and 26 may in practice be a diiferent shape. Plate 25 rests upon resilient member 20 at its depressed horizontal portion, and has its marginal edges terminating close to the 4innermost parts of the curved portions 2|. Upon plate 25 is placed a piece of felt designated as 28, and over the latter member is spread a piece of cloth as 29. An enveloping cloth 30 serves as a covering foi theselatter parts,vthe ends 3| of which extend downwardly between the outer surfaces of the anges 2| of the resilient member 20 and the inner surfaces of the .sides lila om container i0.

It will be `noted that the pad proper extends slightly above the lateral walls Ilia, and it may be positioned lower than the height oi' the walls Illa. When the pad is used a rubber stamp is placed more or'less gently upon the uppermost surface 30. When it is desired to feed the pad proper pressure is applied to the cloth, which pressure is transmitted to cloth 30, cloth 29, felt layer 28, rigid plate 25, and resilient member 2li, and these parts are either slightly or with greater pressure pressed downwardly, and the ink is transferred to the stamp. It will be understood that by this downward pressure action, the ink paste is pumped through the openings 22 and 26 and penetrates the -pad 28 and layers 29 and 30. During this downward pressure the holes 22 and 26, serve to enhance the force of the ink upwardly to the pad 28. Since the member 2li is inherently resilient when'the downward pressure ceases it returns to its original condition, as will be seen in Fig. 2. As the ink contained in the container is gradually used, by each application of the g stamp the member 20 is automatically moved downwardly further by such additional pressure as is necessary to bring about the pumping action described. With suitable pressure the pumping action causes the ink to enter holes 22, even when little ink remains in the container, as the flat portion 20 may be pressed down flush with the bottom of the container; and even with such extended pressure the resiliency of the portions 2| brings the pad back to its initial position. The hinge-like support of the pad proper by reason of the curved parts 2i, causes the use of the pad to be accompanied with a yieldability or'suspension .movement when pressed. by the rubber stamp. This is an agreeable action to the hand holding the rubber stamp.

It will be noted that the pad resembles very ,'closely the ordinary size'pad now generally in use, but in distinction to such standard pads the improved pad is self-feeding by the mere action of the rubber stamp upon the outer face of the pad, and the improved structure permits the use of ink paste or ink cream.

Cloth 29 and rigid member 25 may be dispensed with if a suitable stiilening is given to member 20 by vulcanizing or other means. The curved portions 2| must, however, retain their yieldability and resiliency.

The invention described herein is an improvement over my U. S. Letters Patent No. 2,031,212, dated Feb. 18, 1936, for a Printing pad.
